Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

PRECHARGING OF MAGNETIC TONER WITH MAGNETIC STAINLESS STEEL BRUSH

Publishing Venue

Xerox Disclosure Journal

Abstract

As shown in the drawing, a magnetic brush development system includes a charging brush, indicated generally by the reference numeral 10, having magnetic stainless steel fibers and an electrode to create a high field that the toner particles pass through. The toner particles are deposited on a sleeve 12 having magnet 14 disposed interiorly thereof. As magnet 14 rotates in the direction of arrow 16 , the toner particles are advanced beneath the charging brush and charged positively by induction. The toner is then transferred to an intermediate roll, indicated generally by the reference numeral 18. Roll 18 includes an outer sleeve 20 having a magnet 22 disposed interiorly thereof. As sleeve 20 rotates in the direction of arrow 24, toner particles are advanced into contact with the latent image recorded on the photoconductive surface of belt 26.
